Tehran: Iran`s president on Tuesday sneered at Israeli`s presentation at the UN last week, calling the cartoon-style drawing of a bomb held up by Prime Minister Benjamin Netanyahu "childish and primitive."

Mahmoud Ahmadinejad said the Israeli`s drawing of a red line to urge swifter international action against Iran`s nuclear programme was an intellectual insult to UN dignitaries.

"Red line, white line, black line and the like is for children. This is the level of this guy`s character," Ahmadinejad said at a news conference in Tehran.

"It was a primitive drawing, an insult to the audience ... It was a very ugly behaviour."

The Iranian president used the packed press conference to accuse Netanyahu of being a war-monger, saying of him: "Whoever talks of war is retarded."

At his speech last week before the UN General Assembly, Netanyahu flashed the diagram of a bomb with a lighted fuse to illustrate progress Iran has made in its nuclear programme, saying the country was approaching a threshold Israel could not tolerate.
